This is a new technique for the protection of transmission systems by using the global positioning system (GPS) and fault generated transients. In this scheme the relay contains a fault transient detection system together with a communication unit, which is connected to the power line through the high voltage coupling capacitors of the CVT.

Relays are installed at each bus bar in a transmission network. These detect the fault generated high frequency voltage transient signals and record the time instant corresponding to when the initial ....etc

The recent growth of power circuit capacities has caused fault currents to increase. Since the protection of power systems from the fault currents is very important, it is needed to develop a fault current limiter.

A fault current limiter is required to assure (1) rapid reaction to fault currents, (2) how impedance in normal operation and (3) large impedance during fault conditions. A super conducting fault current limiter (SCFCL) can meet these requirements superconductors, because of their sharp transition from zero resistance at normal cu ....etc

Am rema,want to know about an efficient common mode hybrid filter used in SMPS for my seminar work.


Abstract obtained from IEEE is After the study of electromagnetic interference (EMI)
mechanisms in switching mode power system (SMPS) and the soft
switch, this paper proposes a novel hybrid filter (HEF) to suppress
commend mode EMI in SMPS. The HEF consists of a passive filter
and an active filter. Matching network, which can reduce
impedance mismatching effects, is introduced in passive part. A

HIGH-DENSITY EMI FILTER DESIGN FOR DC-FEDMOTOR DRIVES



INTRODUCTION

Electromagnetic interference (EMI) is one of the major design challenges in motor drive systems, especially in applications where stringent standards need to be followed. EMI noise is usually defined as common-mode (CM) and differential-mode (DM) noise. CM noise is defined as the noise flows between the power circuit and the ground, while DM noise is defined as the current following the sam ....etc
